Need An Idea For Your Next Kickstarter? Check Out This Kickstarter!

META

Kickstarter has become the most powerful force in kickstarting new hardware projects, video games, documentaries, and board games, and now everyone wants a piece of the action. The problem obviously isn’t product development and engineering; you can just conjure that up with a little bit of Photoshop and some good PR. The only you really need for a good Kickstarter is an idea, and META is just the tool for the job. It’s the Arduino-powered Motivational Electronic Text Adviser, the perfect device to generate the next big idea in the world of crowdfunding.

The Arduino-powered META includes three buttons and an Arduino-controlled LCD display. Press a button, and the next big hardware project to wash across the blogs faster than the announcement of a campaign for a $300 3D printer will appear on the screen.

Because META is Arduino-compatible, it’s compatible with existing Arduino sketches. This makes turning the META into the next home automated Bluetooth low energy 4.0 internet of things a snap. Because this is open hardware the laser cut enclosure can easily be upgraded to an RGB LED 3D printer robotic drone bluetooth boombox.

If Kickstarters aren’t your thing, there’s also a cloud-based META that will generate ideas in the mobile app browser cloud. Bitcoin.

I2S Audio And SPI Display With An Ethernet Module

LCD[kgsws] is working on a small project that requires some audio and a display of some sort. While this project can be easily completed with a bigish microcontroller or ARM board, he’s taking a much simpler route: the entire project is built around a cheap router module, giving this project amazing expandability for a very meager price.

The router module in question is the HLK-RM04 from Hi-Link, commonly found via the usual Chinese resellers for about $25. On board this module is a UART, Ethernet, and a WiFi adapter along with a few GPIO pins for interfacing with the outside world.

[kgsws] is using the native SPI pins on this module to control the clock and data lines for the tiny LCD, with a GPIO pin toggling the chip select. I2S audio is also implemented, decoded with an 8-bit DAC, the MCP4801.

It’s an extremely inexpensive solution for putting audio and video in a project, and since this board has Ethernet, WiFi, and a few more GPIO pins, it’s can do much more than whatever [kgsws] is planning next.

Electromagnetic Spiderman Webshooter Railgun / Grappling Hook

spiderman grapple hook rail gun

As technology continues to advance, make-believe props and technology from movies are coming closer and closer to reality. [Patrick Priebe] has managed to put together a working Spiderman Webshooter with the help of electromagnets!

He’s built a tiny rail gun that puts out 100 Joules of energy using a 350V capacitor bank, which straps cleanly to his wrist over top of a Spiderman costume glove. It makes the classic high-pitched hum as it charges, and launches a small barbed brass arrow capable of skewering Styrofoam.

He didn’t stop there though! He’s created a handy little winch using a small high-powered brushless motor with an ESC. A weighted disk acts as a flywheel to increase the pulling power of the fishing line, and he’s built it on a pivot so when you launch it, the fishing line just slips off the end without resistance. To engage, you flip it back perpendicular to the line and turn on the motor.

HummingBoard, The Vastly More Powerful Raspi

 

Humming

The Raspberry Pi has been around for a while now, and while many boards that hope to take the Pi’s place at the top of the single board ARM Linux food chain, not one has yet succeeded. Finally, there may be a true contender to the throne. It’s called the HummingBoard, and packs a surprising amount of power and connectivity into the same size and shape as the venerable Raspberry Pi.

The HummingBoard uses a Freescale i.MX6 quad core processor running at 1GHz with a Vivante GC2000 GPU. There’s 2GB of RAM, microSD card slot, mSATA connector, Gigabit Ethernet, a BCM4329 WiFi and Bluetooth module, a real-time clock, and IR receiver. There’s also all the usual Raspberry Pi flair, with a 26 pin GPIO connector, CSI camera connector, DSI LCD connector,  stereo out, as well as the usual HDMI and analog video.

The company behind the HummingBoard, SolidRun, hasn’t put a retail price on the board, nor have they set a launch date. You can, however, enter a contest to win a HummingBoard with the deadline this Friday. Winners will be announced in early May, so maybe the HummingBoard will be officially launched sometime around then.

It’s an amazing board with more than enough power to rival the extremely powerful BeagleBone Black, with the added bonus of being compatible with so many of those Raspberry Pi accessories we all love dearly.

Sci-Fi Contest Roundup: Doctor Who

doctor-who-logo

What’s a Sci-Fi contest without entries from the longest running sci-fi TV show, Doctor Who?

Sonic Screwdriver Door Lock

Sonic Screwdriver Lock

Ah yes, the iconic Sonic Screwdriver, able to get the Doctor out of almost any jam — with style.

Started this project over a year ago, [Daniel] figured a Sci-Fi contest was a good enough excuse to get around to finishing it.

Using a Raspberry Pi and a microphone, the lock unlocks when the python script detects a sound signature that matches previously recorded Sonic Screwdriver’s hums — meaning friends with novelty Sonic Screwdrivers can join in the fun too — if he lets them.

When the correct sound sample FFT is detected, the door is unlocked using a transistor that is connected to an electronic door strike. When completed you’ll be able to show off your true Whovian nature, and impress your friends!

Head Tracking Augmented Reality Police Box

Head Tracking TardisInspired by the augmented reality TARDIS that is actually bigger on the inside, [Mike] and his wife are working on creating one that doesn’t need a smart phone to enjoy.

Instead it uses head tracking and an LCD inside the door to create the illusion of a cavernous inside! A head tracking Tardis!

A webcam tracks your head’s position, which then changes the perspective of the interior of the TARDIS on the LCD — we’re getting giddy just thinking about it!

EXTERMINATE EXTERMINATE EXTERMINATE!!!

Dalek

While there isn’t too much information on this project, [th3c4rd] is planning on creating a Doctor Who Voice Modulator which will allow you to sound like your favorite villains with the press of a button!

Using a ring modulator for the effect, [th3c4rd] plans on making his own, since commercial ones will run you upwards of $200!

He’s still looking for a team-mate for the project so if you’re interested in helping out, get in touch!

Still haven’t entered the contest? Don’t worry — there’s still time for you to put an awesome Sci-Fi project together to win some crazy cool prizes!

 

 

 

2048: Embedded Edition

Embedded touch version of 2048 tile gameHow ’bout that 2048 game? Pretty addictive, huh? Almost as addictive as embedded systems are, at least if you’re [Andrew]. Armed (pun intended) with a Nucleo F4 and a Gameduino 2 shield, he decided to have a go at making an embedded version of the popular tile pusher web game.

If you’re unfamiliar with the Nucleo boards from STMicroelectronics, check out our post on the Nucleo family from a couple of months ago. The Gameduino 2 shield ships with a 4.3″ touchscreen driven by an FT800 GPU EVE. [Andrew] wrote his own driver for it and his blog post goes into great detail about its programming model and the SPI read, write, and command functions he wrote. Full code is available from [Andrew]‘s repo.

He started by generating a blank screen based on clues found in the Gameduino 2 source. Pretty soon he had rendered a rectangle and then a full 2048 board. A minor difference between [Andrew]‘s creation and the original is that his always creates new tiles as ’2′ while the web game cranks out the occasional ’4′.

We were unable to embed [Andrew]‘s gameplay videos, but you’ll find two on his blog.

 

Retrotectacular: The Science of Derailing Trains

retrotechtacular-derailing-trains

Look closely above and you’ll see there’s a section of track missing. There are actually two, a section from each side has been plucked out with a pair of eight-ounce plastic explosive charges — and yet the train keeps barreling onward. The World War II era reel is demonstrating some military testing of the effect of damaged tracks on a train. The amount of missing track the train can stand up to came as quite a surprise for us!

The test setup itself is neat. An old derelict locomotive is used. It, as well as a number of trailing cars, is pushed by a functioning engine from behind. Once up to about 26 MPH the pusher stops and the rest keep going. There are many tests, starting with just a few inches of track missing from one side. This gap is increased, then gaps are added both sides, then the two sides are offset. Even a 5-foot gap is crossed easily by the locomotive. The weak link turns out to be the empty cars. We suppose their mass is small enough that they can’t rely on inertia to keep them on the straight path.

If you don’t appreciate the destructive nature of this Retrotechtacular installment, you can still get your train fix. There is another offering which shows off the modernization of a signaling system.
